Ground-Based Detections of Thermal Emission from Very Hot Jupiters

Direct detection of flux from planet from secondary eclilpse depth Hottest planets: thermal emission dominates - depends on albedo, energy redistribution Spitzer obs. reveal fundamental dichotomy pM: optical absorbers, thermal inversion (hot stratosphere)

  1. Direct detection of flux from planet from secondary eclilpse depth Hottest planets: thermal emission dominates - depends on albedo, energy redistribution Spitzer obs. reveal fundamental dichotomy pM: optical absorbers, thermal inversion (hot stratosphere) pL: cooler, absorbers condense out; no thermal inversion Atmospheric models make predictions of optical / NIR spectra, can be tested with ground-based instruments Ground-Based Detections of Thermal Emission from Very Hot Jupiters Justin Rogers, JHU Daniel Apai, STScI; Mercedes Lopez-Morales, CIW-DTM; Michael Sterzik, ESO; David Sing, IAP

  2. 15 Transiting Exoplanets hot enough to detect from Earth in optical / NIR Tp = 1200 - 2900 K • Sites / Instruments: VLT / HAWK-I VLT / FORS2 Magellan / MagIC-E2V ARC3.5m / NICFPS Others… • Published Detections Sing & Lopez-Morales (2009): OGLE-TR-56b, z’, FORS2 & MagIC-E2V de Mooij & Snellen (2009): TrES-3b, K, WHT/LIRIS
